Abstract

Det blir beskrevet en forbedret elektrode for administrering av medikamenter ved hjelp av Iontoforese. omfattende et ledende element (22) for mottak av en elektrisk strøm fra en strømkilde; et retlkulert element (20) med et flertall retlkulum for mottak av en ionlsk medikamentoppløsnlng for lontoforetlsk levering, hvor retikulumstrukturen blir lastet med, eller er påført derpå, en hydrofil polymer som er viskøs når hydrert; og midler (24) for festing av det retikulerte element til det ledende elementet slik at elektrisk strøm vil bli distribuert, hovedsakelig uniformt gjennom det retikulerte elementet når strøm blir levert til det ledende elementet. Den for tiden foretrukne utførelsesformen benytter et åpencellet polyuretanskum som det retikulerte element (20), og polyetylenoksyd med høy molekylvekt som den hydroflle polymer. Retiku- i lum er videre lastet med et overflateaktlg middel som tjener til å forbedre hydrerlngshastigheten.
